Closing this issue because it can't be re-pro'ed.

@alanna-zhou, the minimum walking time should always be at least one minute, so the screenshot above demonstrates a different issue!

ah okay, thanks for catching that @young-k! wasn't completely sure if a minute was supposed to be added on there since it's about like 40 seconds to walk 70 feet, so i'll be re-opening the issue now
